vSHOE-HEELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 261,145, dated July 18,1982.

Application filed May 1, 1882.

.To all whom 'it may concern:

Be it known that we, MARTIN VAN BUREN ETHRIDGE and FRANK NEWELLETHRIDGE, of Lynn, in the county of Essex and State of Massachusetts,have invented an improved machine for securing heels to boots and shoesand preparing said heels preparatory to their application to the sole,of which the following is a specification.

Ourinvention relates to an improved machine fornailing heels on boots.and shoes; and it consists in an upright frame supporting a centralbed-plate, to the upper surface of which is attached an adjustablelastin g-jack, the lower end of which is beveled at such aninclination as to facilitate the elevation and depression of said jackthrough the medium of aninclined block or wedge upon which it rests,said wedge traveling in a suitable opening through the base of thelasting-jack standard, and operated by a screw the end of which has acircumferential slot for the reception of a stop-pin, which pin attachessaid screw to the standard, the rotation of the driving-screw operatingthe wedge. The under side of the bed-plate has journals supporting ashaft upon which is mounted a driving-gear and rotating cam, the latteraeting upon an inclined plane movable through the action of a foot-leverand supported upon a block forming part of the lower gate-head, whichgate is sustained by two guide-rods and operated by said cam in avertical direction.

Secured to the under side of the upper gatehead is an adjustablemetalheel-plate provided with asmooth and an indented floor, one upon alower plane than the other. The indented floor is provided withaprojection suiting the form of the heel to be attached, and having twospurs whose office is to retain the heel in proper position beforethenails are driven. In the downward motion of the gate, by action of thecam, said adjustable plate is brought in juxtapositiouwith thenail-prepared heel held by the operator upon the shoe or boot previouslyplaced over the last, when the nail-heads engage in the indentations inthe aforesaid plate and are steadily driven into the sole, the distanceof the nails driven being governed by the height of the heel-shapedmetal projection above the indented floor. This operation permits thenails to remain exposed a sufficient (No model.)

length to receive and secure the top lift at the next rotation of thecam and consequent downward movement of the gate, the adjustableheel-plate meanwhile beingmoved forward by the hand of the operator sothat the smooth floor of said plate may come in contact and press theface or top-lift upon the nails and complete the operation.

To the upperfloor of thebed-plate is attached a device to insure theregular adjustment of the wedge supporting the lasting-jack, and also tomark the dimension of the heels, consisting of a fixed measure or rule,over which moves an adjustableindexpointsecured in any position to themeasure by a nut and screw.

On the left side of the machine, and forming part of the same, isarranged a method of piercingthe heels preparatory to receiving thenails, consisting of a plate to which is rigidly fixed a gang of awls,said awl-plate forming part of a hollow shaft secured to an armprojecting through a slot in the frame, and moved by and with theguide-rods supporting the, gate, to which it is secured. Adriving-rodrigidly keyed at one end to a suitable projection on the frame operatesin the hollow chamber of the awl-shaft when the latter is driven up withthe gate, and forces the leather heel from contact with the awls.

Furtherimprovementsin detail are described hereinafter.

Referring to the drawings, Figure 1 represents a rear elevation of myimproved heelingmachine. Fig. 2 is an isometric proj ection thereof.Fig. 3 is a transverse section of bedplate, wedge, and lasting-jack onthe line m,

Fig. 1. Fig. 4 embraces views of the heel-plate, I

in perspective, plan of face, and section.

A A indicate the side frames, united by the cross-head B and tie-rods BB.

O is a bed-plate, through which right and, left guide-rods D D pass,supporting the gate heads E and E.

F F are powerful lifting springs sea-ted against the collar G and withina suitable re cess, G, in each end of the bed-plate O.

H is the main shaft, to which is keyedthe pinion-gear 1, Fig. 1, whichtransmits its power to the large gear-wheel J, mounted upon thecam-shaft K, journaled at L L in bearings projected from the under sideof bed-plate 0.

M is a cam rotating upon the wedge N, said wedge sliding upon the block0, 'formingpart of the gate E.

P is the upper arm of the lever adjusting the wedge N. P is an elongatedslot in the upper end of said lever, permitting a free movement of thesame in the act of throwing in and out the wedge N, engaging with thecam M.

Q is the fulcrum of the levers I? and B, said levers working in theordinary manner by the foot of the operator at S.

T is a throwing-spring insuring the disengagement of the wedge N withthe cam M.

U U are guides confining the base of the standard V, supporting thelasting-jack W, whose lower end is beveled, as at X, Fig. 3, to suit theincline Y, which is operated and adjusted by the driving-screw Z, theend of the same being atttached to the base of the standard V by thedetaining-pin Z traveling in a circumferential slot near the end of saidscrew.

(1-, Fig. 4, indicates the adjustable heel-plate, formed with beveledsides to fit corresponding guides in the under, side of the gate-head E,Fig. 2.

b is the indented floor, so formed to receive the heads of the nails andhold them in a pen pendicular direction while the leather heel is belingpressed or driven upon the shoe orboot so e.

dis a projection formed upon the indented floor, and provided with spurse c to hold the heel firmly in the proper position.

0 is the smooth floor of the plate, so made to press the top-lift uponthe heel without blemish, concealing the nails and completing theoperation of heeling.

Z is a fixed'rnle or standard, provided with an adjustable indeX-point,a, secured at any desirable height by the nut and screw 1).

findicates a gang of awls firmly attached to a projection, g, whichprojects through and travels in a slot, h, in the frame A of themachine, said projection being rigidly fixed to the guide-rod D andmoving with it.

t isadriving-pin over which the hollow stern supporting the awlsfmovesupward and disengages the heel from the awls, which have pierced it forthe reception of the nails.

Having explained the operation and construction of our improvedinvention, what we claim is- 1. In an improved machine for preparing andnailing heels, the adjustable lasting-jack W, having an inclined foot orrest. X, operating in combination with the wedge Y and drivingscrew Z,substantially as and for the purpose specified.

2. The hand adjusting heel-plate 0!, having a smooth floor, 0, andindented floor b, provided with the heel-driving plate at and spurs e e,for the purpose specified.

3. In combination with thelasting-jack W, the stationary measure Z,having a movable index-point, n, as set forth.

4. The wedge N, moving on the block O,operated by the lovers P R, incombination with the cam M, producing the vertical movement of the gateE E, substantially as specified.

5. The combination of the heel-piercing device f, actuated by theguide-rod D through the slot h, and operating outside of the frame A, asset forth.

6. The combination of the adjustable lasting-jack "W, the movableheel-plate a, and upper gate-head E, all arranged substantially as setforth.
